Frequently Asked Questions
Does this preserve the order of my list?
Yes — the first occurrence of each unique line is kept in its original position; later duplicates are removed.
What counts as a duplicate?
By default, lines are compared after trimming leading/trailing whitespace. You can also enable case-insensitive matching so "Apple" and "apple" are treated as the same line.
